As shown in FIG. 3, the smart camera 300 can be in circuit communication with the diagnostic tool 100, or other pass through devices, via a serial port, USB (universal serial bus), BLUETOOTH, FIREWIRE, etc., and transmit images back to the diagnostic tool 100 or a computing device 350, where the images or video will be displayed.

The connection between the smart camera 300 and the diagnostic tool 100 can be wired or wireless using the various methods of connection and protocols as discussed herein. In an alternative, the camera can be built into the diagnostic tool itself (401 of FIG. 4). The communication can be bi-directional or mono-directional. The smart camera 300 can be used to take pictures of the various parts of the vehicle include the parts that may be faulty. The smart camera 300 can also be used to take a picture of the vehicle or device that the part is used for. This way the vehicle or device can also be identified using a database (vehicle or device, etc.) similar to the ones described herein. The smart camera can be used to train technicians including using the smart camera to take pictures of how the parts fits in the vehicle and its location so that the technician can be use the pictures to put the parts back in the proper place if needed.

In one embodiment, the technician can use the smart camera 300 to take a picture of a faulty part. A parts image database 412 (FIG. 4) stored on the diagnostic tool or remotely can be used to identify the part by using image recognition software. The image database can contain images of the parts or other information such as bar code information, etc. Certain portions (identifying points and measurements) or the whole profile of the part can be used to compare the part to images of parts of a vehicle or device stored in the parts image database. The image recognition software should be able to use various characteristics of the part to conduct the search. These characteristics include measurements of the part, wiring, connections, color(s), contrast (part versus the background of the vehicle), surface characteristics of the part, etc.

The search of the parts image database will proceed faster if the vehicle (or device) identification information for the vehicle (or device) under test is entered into the diagnostic tool so that the search is limited to the parts of the entered vehicle (or device). The vehicle identification information can include the VIN (vehicle identification number), make, model, year or other vehicle identifiable characteristics (hybrid, electric, etc.). Other search parameters can be used to narrow down the search such as major categories such as transmission, brake, interior, exterior, etc. Once the search identifies the part(s), the information related to the part can be displayed on a display screen of the diagnostic tool (other computing device) for verification by the technician. Optionally, the camera's display can also be used to display the information. In other embodiments, the image (and other information) can be sent to a smart phone so that the technician can have a portable image with him at the parts store. The information can include the part's number, diagrams on how to remove and replace the part, diagrams on where the part is located on the vehicle, manuals for the part, specifications about the parts, warranty information, oem (original equipment manufacturer) equivalent parts, etc. Once properly identified, additional information such as parts availability, pricing, location, etc. can be retrieved as discussed herein.

In another embodiment, the smart camera 300 also can function as bar code reader by being able to “read” bar codes on a part, for example. This may be completed through focusing the smart camera's lens on the bar code and then taking an image of the bar code. The bar code image or the information converted from the bar code image can be used to search to the parts image database. Once identified, the bar code information can provide information such as the part's number to the technician. Further, information such as parts availability, pricing, location, etc. can be retrieved as discussed further below.

FIG. 4 is a block diagram of the components of the diagnostic tool 100 according to an embodiment of the invention. In FIG. 4, the diagnostic tool 100 according to an embodiment of the invention includes the smart camera 401, a processor 402, a field programmable gate array (FPGA) 414, a first system bus 424, the display 102, a complex programmable logic device (CPLD) 406, the input device in the form of a keypad 404 (scroll device), a memory subsystem 408, an internal non-volatile memory (NVM) 418 having the parts image database 412, a card reader 420 (optional), a second system bus 422, a connector interface 411, a selectable signal translator 410, a GPS antenna 432, a GPS receiver 434, an optional altimeter 436 and wireless communication circuit 438. A vehicle communication interface 430 of the vehicle under test is in communication with the diagnostic tool 100 through connector interface 211 via an external cable (not shown).

Selectable signal translator 410 communicates with the vehicle communication interface 430 through the connector interface 411. Signal translator 410 conditions signals received from an ECU unit through the vehicle communication interface 430 to a conditioned signal compatible with diagnostic tool 100. Signal translator 410 can communicate with, for example, the following communication protocols: J1850 (VPM and PWM), ISO 9141-2 signal, communication collision detection (CCD) (e.g., Chrysler collision detection), data communication links (DCL), serial communication interface (SCI), Controller Area Network (CAN), Keyword 2000 (ISO 14230-4), OBD II or other communication protocols that are implemented in a vehicle.

The circuitry to translate and send in a particular communication protocol can be selected by FPGA 414 (e.g., by tri-stating unused transceivers) or by providing a keying device that plugs into the connector interface 411 that is provided by diagnostic tool 100 to connect diagnostic tool 100 to the vehicle communication interface 430. Signal translator 410 is also coupled to FPGA 414 and the card reader 420 via the first system bus 424. FPGA 414 transmits to and receives signals (i.e., messages) from the ECU unit through signal translator 410.

The FPGA 414 is coupled to the processor 402 through various address, data and control lines by the second system bus 422. FPGA 414 is also coupled to the card reader 420 through the first system bus 424. The processor 402 is also coupled to the display 102 in order to output the desired information to the user. The processor 402 communicates with the CPLD 406 through the second system bus 422. Additionally, the processor 402 is programmed to receive input from the user through the user interface 404 via the CPLD 406. The CPLD 406 provides logic for decoding various inputs from the user of the diagnostic tool 100 and also provides glue-logic for various other interfacing tasks.

Memory subsystem 408 and internal non-volatile memory 418 are coupled to the second system bus 422, which allows for communication with the processor 402 and FPGA 414. Memory subsystem 408 can include an application dependent amount of dynamic random access memory (DRAM), a hard drive, and/or read only memory (ROM). Software to run the diagnostic tool 100 can be stored in the memory 408 or 418, including any other database. The database can include diagnostic information and other information related to vehicles.

In one embodiment, the parts image database can be located on a remote computing device instead of being local on the diagnostic tool. The remote parts image database can be accessed via a wireless or wired connection. The remote parts image database can also be stored on an external memory, such as a compact flash card or other memories and accessed locally by the diagnostic tool.

Internal non-volatile memory 418 can be an electrically erasable programmable read-only memory (EEPROM), flash ROM, or other similar memory. Internal non-volatile memory 418 can provide, for example, storage for boot code, self-diagnostics, various drivers and space for FPGA images, if desired. If less than all of the modules are implemented in FPGA 414, memory 418 can contain downloadable images so that FPGA 414 can be reconfigured for a different group of communication protocols.

The GPS antenna 432 and GPS receiver 434 may be mounted in or on the housing 101 or any combination thereof. The GPS antenna 432 electronically couples to the GPS receiver 434 and allows the GPS receiver to communicate (detects and decodes signals) with various satellites that orbit the Earth. In one embodiment, the GPS antenna and GPS receiver are one device instead of two. The GPS receiver 434 and GPS antenna 432 electronically couple to the processor 402, which is coupled to memory 408, NVM 418 or a memory card in the card reader 420. The memories can be used to store cartographic data, such as electronic maps. The diagnostic tool can include all the maps for the U.S. (or country of use), North America or can have the region or state where the diagnostic tool is located. In alternative embodiments, the diagnostic tool can have all the maps of the world or any portion of the world desired by the user. This allows the diagnostic tool to be a GPS device so that a driver can drive from one location to another. The maps may be over lay or incorporates with traffic, local events, and location of other GPS devices (smart phones) and other information that can be useful to the technician. By being able to locate other diagnostic tools with GPS, then the technicians may be able to use the diagnostic tools to locate each other in order to conduct a meeting or have a social event.

The GPS receiver communicates with and “locks on” to a certain number of satellites in order to have a “fix” on its global location. Once the location is fixed, the GPS receiver, with the help of the processor, can determine the exact location including longitude, latitude, altitude, velocity of movement and other navigational data of the diagnostic tool 100.

Should GPS receiver be unable to lock onto the minimum number of satellites to determine the altitude or unable to determine the altitude for any reason, the altimeter 436 can be used to determine the altitude of the diagnostic tool 100. The altimeter 436 is electronically coupled to the processor 402 and can provide the altitude or elevation of the diagnostic tool 100. The altimeter 436 can be coupled to a barometric pressure sensor (not shown) in order to calibrate the elevation measurements determined by the altimeter. The sensor can be positioned interior or exterior to the housing 101 of the diagnostic tool 100. Minor atmospheric pressure changes can affect the accuracy of the altimeter, thus, diagnostic tool can correct for these changes by using the sensor in conjunction with the altimeter along with a correction factor known in the art.

Wireless communication circuit 438 communicates with the processor 402 via the second bus system 422. The wireless communication circuit can be configured to communicate via RF (radio frequency), satellites, cellular phones (analog or digital), Bluetooth®, Wi-Fi, Infrared, Zigby, Local Area Networks (LAN), WLAN (Wireless Local Area Network), other wireless communication configurations and standards or a combination thereof. The wireless communication circuit 438 allows the diagnostic tool to communicate with other devices wirelessly such as with a remote computing device 500 (FIG. 5) having remote databases. In one embodiment, the database includes the parts image database 550 (FIG. 5). The wireless communication circuit 438 includes an antenna built therein and being housed within the housing 101 or can be externally located on the housing 101.

FIG. 5 illustrates the tool 100 communicating with the remote computing devices 500, 560, 580 having the remote parts imaging database according to another embodiment of the invention. As previously stated, the tool 100 includes the ability to access the remote computing devices via a wired or wireless connection. In this embodiment, the tool 100 is wirelessly communicating with the remote computing device 500 that stores the parts image database in the event the additional information is not stored locally on the diagnostic tool. In this embodiment, the parts image database can be used to search for the correct part and parts number based on the images captured by the smart camera including the bard code image.

The remote computing devices 500, 560, 580 can be located in the garage that the tool 100 is being used or located in another location such as another building, another part of the city, another city, county, state or country. The wireless connection can also be via a distributed network, such as the Internet.

In one embodiment, the remote computing devices 560, 580 may be parts suppliers computing devices that contain respective parts information databases. The parts information can include pricing, warranty, availability, diagrams, manuals, delivery options including mailing and local delivery, and other parts information. Thus, once the part(s) that needs replacement is identified, the parts supplier's computing devices 560, 580 that contains the parts databases 570, 590 (respectively) can be accessed to determine the price and availability of the part. The GPS location of the diagnostic tool can be used so that the nearest part supplier can be located with the part available for purchase and the best price. This will save time and provide options so that the technician can choose to travel to the parts store to purchase the part, have the part delivered locally or shipped by interacting with a web site stored on the parts supplier's computing device, or simply place it on hold for pick up when desired. Additionally, other parts stores that have the part available can also be displayed so that the technician has a choice to go other stores in the event he has to run other errands or is on the way home or returning back to work.

FIG. 6 illustrates the steps of identifying and obtaining information for a part that needs to be replaced according to an embodiment of the invention. The method of indentifying and obtaining information about the part 600 starts at step 602. At step 602, the smart camera can be used to take an image of the part that needs to be replaced or identified. The smart camera can simply take a picture of the part or if the bar code is available, then the smart camera can take a picture of the bar code. At step 604, a search of the parts image database is conducted. The parts image database can be located on the diagnostic tool 100 or on a remote computing device 500 or both. At step 606, the diagnostic tool and/or the remote computing device 500 can identify the part and provide the part information such as the part number, the amount of the part that would be needed to be replaced or other part identifying characteristics. For example, it is recommended to replace two tires or shocks at a time instead of one. The location of where the part (and indirectly the technician) is located can be determined based on the GPS coordinate of the diagnostic tool 100 using the tool's GPS components.

At step 608, the diagnostic tool or the computing device 500 can communicate with the parts suppliers' computing devices 560, 580 to search for the part. At step 610, the part is identified based on the information sent to the parts suppliers' computing devices. At step 610, the part information can be displayed to the technician on a display of the diagnostic tool 100 or remote computing device 500 or the camera. The part information can include pricing (costs, retail, discounted, etc.), availability including the location of the parts and if not available, alternative locations of the part or when the part is expected to be available and if there are alternatives (generic parts) that are available for the original equipment manufacture part. At step 640, the technician can take action depending on the information displayed to him including ordering and purchasing the part to be delivered (if locally available) or shipped, or placing the part on hold for pickup at a later time and other actions. Alternatively, the technician can take no action based on the information provided or any other reason. The method ends at step 640.

The embodiments described herein can be used in other areas beyond vehicle and their components. Other areas include devices, buildings or anything that have components that are replaceable such as computing devices, and refrigeration devices, heating devices, etc.
